NOTE: This is a current WIP (work in progress).
Abliteration method:
1. Obtain refusal direction with llama-cpp-python.
2. Orthogonalization performed with torch directly to .safetensors. (one at a time)
It is a rather larger model so it may take me another day or two to figure out which layer I should be using for the direction vector.
First attempt: Layer 20 was used to obtain refusal direction vector. Refusal mitigation sort of worked but not perfect.
Second attempt: (Current) Layer 23 was used (mid-point of model). Half-way has proven to work with other model so this should be fine.
